New Hummer has crazy good specs. 1000 HP and 1150 torque.

Torque is always HP / RPM x 5252, it's law of physics that applies to any angular "force". In metric terms, torque (n-m) = power (watts) / rad/sec.

While meaningful to portray the shape of power curve on IC engines, torque becomes useless on electric motors. Motors by nature are nearly constant hp, with an inverse torque curve, i.e. immense torque rise.

Close to 0 rpm, a theoretical motor would have infinity torque. In real life, you're limited by current capacity of the motor windings.

The EV torque rating at the wheels is only meaningful to measure tractive effort, not motor performance. 11,500 lb-ft, with say 35" tires, roughly translates to 7886 lbs of tractive effort (assuming the truck weighs enough). How long it maintains that depends on the duty cycle of the motors at max torque (winding current).

However, 1000 hp, if true, is nothing to sneeze at...

Horsepower is not the force that does the work, torque is.

HP is a measurement of work over time. It is the speedometer.

To compare directly the combustion engine vehicle’s torque capability at the drive wheel ends from a standing start without breaking traction should be calculated as ShinerBock says. It is easy to do with manual trans. More math is needed with torque converter auto trans’sz.

I tried out 2 electric motorcycles. One of them might even do 0 to 60 in 2-1/2 secs can’t remember. That’s normal for fast bikes. Anyway they were super quick and boring as hell to ride on the road.

Electric drive is a good deal for “appliance” vehicles requiring low pilot input / skill. Like golf cars, the drive or ride experience isn’t the object of the exercise.

1,230 lb-ft at the crank(level 4 tune) X 3.23 first gear X 3.42 rear axle ratio = 13,587 lb-ft at the wheels

Engineered Explained HERE touched on this during his video on the Bronco crawler gear. That the electric vehicle manufacturers quoting their wheel torque is misleading.

The difference is that the Electric Vehicle has all it's torque available from zero RPM all the way to the top speed of the vehicle. Not that it matters for tow vehicles, but that is the major reason internal combustion vehicles get waxed by electric vehicles in a drag race.

The electric version might have a tolerable reputation if they can keep it on the road with all that power.

Our neighbours in Palm Springs have one. He has heat it in excellent. It’s essentially their grocery getter. Quite iconic looking. He paid something like 1600 bucks for a new exhaust systym last year. Kinda cool looking though. Lots of chrome.

I didn't see anything about the range of the electric Hummer. It does say quick recharge.

ShinerBock, is torque/HP calculated the same on an electric motor as a diesel engine?

My guess is those buying an estimated 100,000 dollar SUV probably won’t care about getting something like 60 mpgE. :)

And all the above waaaay above my pay grade.

Zero to 60 in 3 seconds seems pretty quick though. :).
